| Abstract | Ba1−xPrxCo1−yFeyO3−delta (BPCF) perovskite oxides have been synthesized and investigated as cathode materials for low temperature solid oxide fuel cells (LT-SOFCs). Compared with those of Ba0.5Sr0.5Co0.8Fe0.2O3−delta (BSCF) and Sm0.5Sr0.5CoO3 (SSCo) cathode materials, BPCF has a lower polarization resistance at decreased temperatures. In particular, Ba0.5Pr0.5Co0.8Fe0.2O3−delta showed the lowest polarization loss among the different compositions as a cathode material for LT-SOFCs. The area specific resistance (ASR) of Ba0.5Pr0.5Co0.8Fe0.2O3−delta as a cathode material is 0.70 and 0.18 Omega cm2 at 500 ◦C and 550 ◦C, respectively. The maximum power density of the cell BPCF/SDC/Ni–SDC with humidified hydrogen as fuel and air as oxidant reaches 860mWcm−2 at 650 ◦C. |
